Towards the years leading up to the Battle of Geonosis, Typho was one the few Fett-bred clones that Delta-3530 personally selected to train and serve under him in the 353rd Legion. Like Doxx, Barddock, Aiden, Brock, Pierce, Darnell, and Grayson, Typho would be the second clone lieutenant whom Gohan would personally train, and would become his second right hand man, after Doxx, during the first year of the Clone Wars. Like the others, Typho was trained with Delta-ARC training skills, from Gohan.

As the 353rd Legion operated as an independent military division of the covert black-opps in the Republic Army, Typho, like many other clones that Delta-3530 trained, swore his allegiance to Gohan only, before the Republic.

When Gohan ordered Typho to search for a nickname to identify and call himself by, Typho had difficulty searching for one, as he did not know what name would suit him. Gohan then suggested the name Typho to him and the lieutenant agreed to take it. Gohan later gave command of the 442nd Terrak Company, a detachment company of the 353rd, and assigned Typho and the 442nd to the 41st Elite Legion.
